MK7.5 Golf - Anything I should be wary of?

Looking at a 2018 MK7.5 Golf:

Manual 1.4 TSI SE Nav 122K miles £5K

The last owner has taken care of it very well (Main Dealer Services last 3 years) and it has full service history (mix of Main Dealer & Independent)

The timing belt kit has been done but I think it may need doing again (unsure what the interval actually is - everywhere I've looked has a different answer)

Anything to look out for on this model/engine? Too many miles for a petrol?

I'm upgrading from a MK2 Yaris - want something better on the motorway and more presentable

Any advice appreciated 👍
